Lord Lisvane: My Lords, I am delighted to follow the noble Baroness, Lady Young, whose name stands at the head of Amendment 227A. I will add  just two points in addition to endorsing the unhappiness of the noble Viscount, Lord Hailsham, partly conveyed through his lead amendment and other amendments in this group.
So far, the practicalities of Brexit have been a conversation primarily between government and Parliament. If the use of the sweeping ministerial powers in the Bill will carry credibility with our fellow citizens, that conversation needs to be joined by the huge army of those who will not be directly affected. However—and I think we could all draft the reply of the Minister, just after the headnote that says, “resist”—the possibility of consultation throws into sharp relief the extraordinary pressures of time under which the EU-related parts of the statute book will have to be repatriated and adjusted. Even if there is a two-year period of transition—or implementation; I do not think the two are the same, by any means—a three-month consultation period would be luxurious indeed. Yet effective consultation—that is, beyond the usual suspects—cannot be done quickly.
My second point relates to the relationship between the Lords and the Commons. I cannot help but remark that if Ministers agreed to be bound by the test of necessity rather than appropriateness, their problems in this area might be very much fewer. It seems pretty clear that there will be heavyweight regulations—probably quite a lot of them—for both Houses to consider. As the Bill is drafted at present, there may be too many that are subject to the negative procedure and not enough that are subject to the affirmative procedure, but in any event we will have to focus minds on what will happen if the two Houses disagree.
So far as affirmatives are concerned, I have put my name to an amendment in the name of the noble Lord, Lord Sharkey—Amendment 239A—which explores a possible dispute resolution procedure. However, if major regulations come forward on which there manifestly has been insufficient consultation, the possibility of disagreement between Lords and Commons would increase. Given the inevitable degree of political contention and unyielding pressures on time, this might become a matter of serious concern. I suggest that systematic consultation offers a possible way of reducing that hazard.
